This author contends that there are four key ingredients to a growth mindset in schools: observation, dialog, feedback, and investment. In addition, teachers and supervisors need to be jointly invested in the growth mindset of the school. The author suggests that if a school is considering a new faculty evaluation system, it is crucial that faculty be involved in the process of identifying the core elements of the system and in selecting the tool to use. It is also important to regularly assess an evaluation system as new tools are implemented. A reflective approach will improve the system and increase teacher buy-in. As educators seek to establish their own quality measures and evaluatory mechanisms regarding teaching, they must place them squarely inside a growth-mindset framework. These measures can then be used to attract and retain excellent teachers who feel empowered by a model that both pushes and supports them in their work each day.
